How did herbert spencers belief in the survival of the fittest influence his view of social unrest?

Herbert Spencer believed that society would naturally evolve over time, with the strong and fittest individuals or groups surviving and progressing. He applied this concept, known as social Darwinism, to social unrest by arguing that it was a natural process necessary for society to adapt and improve. Spencer believed that social unrest could lead to positive change by weeding out the weaker elements of society and allowing the strongest to thrive.
